Pesticide residue exceeded, how much harm?

Many people have heard of this saying: “You're not eating when you're not clean.” This is obviously a joke joke, but it also reveals a hint of helplessness. The person who does not want to eat something in his mouth is safe. Reliable, hygienic and healthy. A member of the public, Ms. Zhu, purchased a rapid test card that could quickly detect pesticide residues because she was concerned that the fruits and vegetables bought from the market were not safe. However, when she experimented with tomatoes, she discovered that no matter where they bought the product. To the tomatoes, the test results are "pesticides exceeded." Ms. Chu couldn't help wondering. In the end it was these tomatoes that had pesticide residues. Wasn't a speed test card allowed? In fact, not only tomatoes, but also the fruit that almost everyone loves, has always been questioned. These days, rumors about the safety of strawberries are not uncommon. This makes some people worry: Is eating strawberries really equal to chronic poisoning?

Strawberry

Strawberry is a fruit that many people like very much. However, several recent messages on the Internet have thrown the enthusiasm of the citizens to eat strawberries. There is even such a statement. This argument makes many netizens feel puzzled, so there are so many strawberry pesticide residues?

In order to verify the authenticity of this rumor, the reporter first went to the suburbs to see what farmers and merchants were saying. The reporter visited a number of strawberry plantations in Beijing. Farmers vowed that their strawberries had not been hit with pesticides. They even said that they were organic foods. Pesticides would not be exceeded. Did their strawberries really fight pesticides? No pesticide residue? In order to verify the messages of netizens, the reporter also visited a number of strawberry plantations and found no pesticides in the growers. This inevitably led to doubts.

In the process of growing strawberries, will the pesticides be used in large quantities, as netizens said? We decided to test verification. The reporters randomly purchased 8 strawberry samples from Beijing Xinfadi Agricultural Products Wholesale Market, Midea Supermarket, Changping Picking Garden, and a roadside strawberry stand, and sent them to the Beijing Agricultural College for testing. After preliminary testing by staff, all of the eight samples were detected as pesticides such as chlorothalonil. The highest content is the No. 4 strawberry sample purchased in Shinsei. The lowest content is the No. 7 sample purchased at Changping Picking Garden. Do these residual chlorothalonil pesticides meet national standards?

Although this test detected the pesticide chlorothalonil. However, even if the highest number 4 sample remains, the detection result is only about one-hundredth of the national standard. The lowest No. 7 sample, the detection result is only about five-thousandths of a thousandth of the national standard, and the results are very gratifying. In addition to chlorothalonil, are there any other pesticide residues? The experimenters continued to test, and a professional vocabulary that was not well-known jumped into the field of vision - acetochlor. After further testing, the experimenter detected another pesticide, acetochlor, which was also found in all eight samples.

Strawberry

The highest content is the No. 1 strawberry sample purchased at Shinsei. The lowest content is also the No. 3 sample purchased at Shinsei. That acetochlor pesticides are also in line with national standards? In China, although there is no standard for acetochlor in strawberries, it can be used on some large crops. If we refer to the acetochlor residue standard on these crops, what is the residue of acetochlor on strawberries that we tested? Acetochlor has no standard in the detection of strawberry pesticides in China. We cannot determine whether it exceeds the standard.

According to experts from the Food and Information Exchange Center, acetochlor is a type of herbicide that was first invented by Americans and used in many countries including the United States. China's regulations on acetochlor are very strict and are only allowed in brown rice, corn, soybeans, peanuts, and rapeseed. Residue limits are also lower, but the scope of use of acetochlor in China does not include strawberries. In the EU where the requirements for pesticide residues are more stringent, is there a standard for the use of acetochlor in strawberries? If we refer to the European Union standard of 0.05 milligrams per kilogram, the maximum residue of acetochlor in the sample of strawberry No. 1 is 0.367 milligrams per kilogram, which is more than seven times higher than that of the European Union standard. Even the lowest residual No. 3 sample is Exceeded about 1 times.

What kind of pesticide is acetochlor? If it is overdose, what kind of harm will it cause to the body? Originally, according to experts, the United States has classified acetochlor as a b-2 carcinogen. If acetochlor is consumed for a long period of time, the accumulated amount will be relatively high. Acetochlor residues may cause poisoning of its metabolites. . For example, the poisoning of quinoneimine metabolites may be carcinogenic. Food safety is related to the health of the people and does not allow them to be sloppy. Due to the fact that China's agricultural cultivation has not been scaled up for a long time, farmers often apply excessive amounts of fertilizers and pesticides in pursuit of production, and because the relevant standards are not high enough, law enforcement is not serious enough, and some problems will flow into the market. Food safety is a kind of product and it is also managed. Only the government departments and the majority of growers form a joint force to enable the people to eat reliable food.
